If you haven’t heard by now, there’s another debate making its way around the internet. Some people who listen to the audio file hear “Laurel,” while others hear “Yanny,” and some hear something completely different or even both.

Well, according to the Philly Police Department, it is definitely “Laurel,” but don’t bother calling them to ask.

“Please don’t call 911 to ask if we’re hearing ‘Laurel’ or ‘Yanny,'” said the Philadelphia Police Department on Twitter. “The only thing we hear is the creation of another bad hashtag. (And Laurel. We’re definitely hearing Laurel).”

Please don't call 911 to ask if we're hearing "Laurel" or "Yanny". The only thing we hear is the creation of another bad hashtag. (And Laurel. We're definitely hearing Laurel).
